    Raid 0 pool with 2 disks

    Thanks for the reply that created the ZFS storage. I am building a 2 server simple cluster, is there a command to make the drive show up in the shared Datacenter storage, I want the second server with the 2 drives to be avaialble as a simple replication for the first server. I can blow away the...

    What do you think of my backup strategy?

    ...my parents' house. The PBS will also get a small hardware upgrade: - 512GB SSD (offsite 256GB) for PBS - 16GB RAM (8GB offsite) - 12TB HDD for ZFS backup - 4TB HDD for PBS backup I want to set everything up before Easter and connect it at my parents' house on Easter. Would you use...

    Raid 0 pool with 2 disks

    ...in mind that if you disable the cachefile, the pool won't be imported automatically after a reboot, and you'll have to import it manually via zfs import VM-Drives. That probably isn't a good idea if you plan to run VMs on it. ;) So If you don't want to disable it, just leave the option out...

    Freeze during backup

    No it's just using the "local ZFS mirror on SSDS". The NAS is just used for the backups and only the main host has it mounted.

    Windows Server 2025 mit RDP / Festplatten Geschwindigkeit sehr schlecht

    Single User Kram auf consumer drives - Glückwunsch, wenn es bei Dir läuft. Aber ein Terminalserver ist eine andere Liga als ein User, der ein bisschen surft oder einen Mailclient offen hat. Das sind komplett unterschiedliche Workloads. Und nein, der Punkt bezüglich consumer drives im...

    Windows Server 2025 mit RDP / Festplatten Geschwindigkeit sehr schlecht

    Ja das ist uns bewusst, aber eben 0.1Mbit/s ist auch für eine WD Red massiv zu wenig. Wobei ja der Download der grossen Datei recht flott ging, da würde ich nicht von einem Performance Problem sprechen. Nein es ist kein ZFS im Spiel, das haben wir gewusst das dies keine schlaue Kombo ist.

    Windows Server 2025 mit RDP / Festplatten Geschwindigkeit sehr schlecht

    ...und es läuft Chrome mit xx Tabs und meist noch ein FF. Outlook auch. Und es gibt keine Spikes auf den virtuellen Disks. Ich hab allerdings kein LVM sondern ZFS. :) Das mit dem "Enterprise-SSD-only" halt ich für arg übertrieben. Jedenfalls die hier beschriebenen Symptome haben damit m.E. nix...

    Windows Server 2025 mit RDP / Festplatten Geschwindigkeit sehr schlecht

    WD Red SSD, consumer drives im HW RAID1, da kann man nicht viel an Performance erwarten. Gerade bei virtualisierten Terminalservern mit multiplen User sessions. Ihr habt hoffentlich nicht noch ZFS auf das HW RAID gepackt? Wie sieht denn der I/O delay im PVE aus, wenn die Symptome auftreten?

    ...will be briefly frozen while the data is being dumped, which will inevitably cause a temporary service interruption. It's definitely an easy trap to fall into, especially when you are used to how seamlessly ZFS handles this. Thanks again for taking the time to write this up and warn the...

    What do you think of my backup strategy?

    I correct it to offsite and it is a little bit confusing. I mean, that my offsite is a mini pc with PBS. Therefore I can use ZFS for my storage and therefore I can use versioning etc. for my tfs dataset. This was what I meant, that PBS don't need ZFS but my ZFS dataset.

    What do you think of my backup strategy?

    The functionality and usability of PBS has nothing to do with ZFS. (It does not depend on ZFS and/or ZFS-send/receive.) Yes! And it would be available when the node (which hosts that LXC) dies! Maybe. That is completely up to your expectation/requirement and depends on the actual importance of...

    What do you think of my backup strategy?

    I was about to get started when I noticed that my NAS uses NFS, not ZFS. This isn't a problem for the on-site PBS, but I can only transfer the Nextcloud dataset to the NAS using rsync. Only my offsite PBS could handle versioning with ZFS send and ZFS receive. What do you think? Is this...

    lxc.hook.pre-start script for mounting drives on host

    Did you ever figure this out? Currently hitting adjacent issues for several similar scenarios where specific services need to be available, i.e., a mount, prior to a container being able to successfully start. Mulling writing up a blog post on it if there's interest.
